Merge tag 'dlm-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm
Pull dlm updates from David Teigland:
"This set includes some minor fixes and improvements. The one large
patch addresses the special "nodir" mode, which has been a long
neglected proof of concept, but with these fixes seems to be quite
usable. It allows the resource master to be assigned statically
instead of dynamically, which can improve performance if there is
little locality and most resources are shared."
